Nature and Science are the two most renowned publishers of scientific findings. Now a research paper from the Institute for Electrical Information Technology (IEI) has been published in a Science Partner Journal (SPJ). The research results of a cooperation between the Chair of Measurement Technology at the IEI and the company Sincotect have demonstrated the usability of the potential probe method for monitoring the fatigue strength of metallic bridge structures. In the article "Experimental and Numerical Analysis of the Potential Drop Method for Defects Caused by Dynamic Loads" in the SPJ "Advanced Devices & Instrumentation", it has now been shown how surface cracks on the roadway side can be detected in a targeted manner and with previously unknown resolution using a carrier method when the current is applied and by using the so-called proximity effect via the optimally positioned ground line. These findings are important for the safety of structural infrastructures worldwide and promise a high scientific impact as well as an interesting market for the industrial partner Sincotec in Clausthal-Zellerfeld.
